I think that you can see some of this play out in where/when individuals leave companies. The part of work that is detail oriented, and not creative/conceptual (ie lawsuits and contracts) tends to repel the individuals that only want to work on interesting problems. The engineers of great Software companies move from interesting project to interesting project. The example of Wikipedia vs Encarta may not be the very best example of one work method vs the other. That is more an example of free and easy to access vs pay and limited to access. I am sure that there are great analogies for this type of work, the speaker just didn't choose one.
